Abstract

PURPOSE:To make a device manufacturable with a build-block technique, by constituting it so as to alter length of a strut according to each form and characteristics of supplied parts and to give a tilt to a track surface, in case of the aligning device for a swivel type parts feeder. CONSTITUTION:Works W on a disc 1 are transferred onto a track 4, transferred and they are aligned in a longitudinal direction by an aligning wall 10, while irregular attitudinal works W are dropped on the disc 1. This intermediate disc 20 is supported at three points in a way of installing one strut 31 beneath this aligning part 10 and a strut 32 in other two points, respectively, whereby each length of these three struts 31, 32 and 32 is formed to be variable, and the intermediate disc 20 is constituted to be tiltable in an optional direction centering on the aligning part 10. Thus, the intermediate disc 20 is tilted to some extent according to each form and characteristics of parts whereby these irregular attitudinal parts are made easy to drop down. With this constitution, it is made correspondable to various parts and thus manufacture becomes so easy.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a parts supply machine, and relates to a method for aligning a supply machine described in No. 1983-98994, which was previously filed by the applicant. Parts supply is a factor that determines the success or failure of manufacturing automation systems and labor-saving equipment. The present invention relates to the manufacture of a parts feeder that allows easy alignment according to the purpose of the parts feeder.

Problems to be Solved by the Invention However, the current situation is that parts feeding machines must be manufactured in accordance with the shape and characteristics of the parts to be fed. For this reason, parts supply machines are manufactured one by one, and the design and processing are performed each time, requiring a large amount of labor and funds. The present invention seeks to create an alignment method that is suitable for the characteristics of the parts to be supplied, and by creating a swing-type parts supplying machine with a variable inclination using a build block that can realize this method, it is possible to manufacture a parts supplying machine. The goal is to streamline the process and create a parts supply machine at a low cost.

Means for Solving the Problems Figure 1 is an explanatory diagram of the mechanism of the feeder described in Japanese Patent Application No. 56-98994. A zero disc 1 is connected to a disc drive motor 22 by a rotating shaft 2, and a drop prevention wall 3 that slides on the outer periphery of the disc 1 rotates together with an annular track 4 attached above the drop prevention wall 3. The rotating shaft 2 is fixed to the intermediate disk 20 via a rotating bearing 21. The lower part of the fall prevention wall 3 is attached to the intermediate disk 20 via a bearing 8. The fall prevention wall 3 and the track 4 are connected to a track drive motor 24 via a transmission mechanism 5 below the bearing 8. An outer wall 7 is fixed to the intermediate disk 20 on the outside of the track 4 and at right angles to the plane of the track. An alignment mechanism and an alignment wall 10 for aligning supplied parts on the outer wall 7 are attached to the zero-disc drive motor 22 and a truck drive motor 24, which are attached to the intermediate disk 20 by members not shown.

Disc l, track 4, fall prevention wall 3. The structure shown in FIG. 1 in which the outer wall 7 and the rotating shaft, bearing, drive motor, etc. attached thereto are attached to the intermediate disk 20 is called an upper structure. FIG. 2 is a cross-sectional view of the present invention in which struts are attached to the superstructure and fixed onto a base. 2 to intermediate disk 20
More than one pillar 31.32 is attached to the pillar 31.32.
32 is fixed to the base 30. FIG. 3 shows an example in which the supports are made of three pieces of wood, and by appropriately adjusting the lengths of the supports 31, 32, and 33, the upper structure can obtain an optimal inclination for alignment. In order to adjust the length of this column, the column is made to have an expandable structure and is adjusted according to the parts to be supplied. Furthermore, it does not change the spirit of the present invention to prepare in advance various types of supports with different lengths and to adjust the inclination of the intermediate disk by selecting them.
In addition, with the length of the pillar constant and the angle of the intermediate disk with respect to the base 30 constant, a member is inserted under the base 30.
It does not change the spirit of the present invention to change the angle of the intermediate disk 20, that is, the track 4, with respect to the earth by changing the angle of the intermediate disk 20 with respect to the earth.

There are many methods for alignment, depending on whether or not the center of gravity of the supplied parts is within the plane of the truck. Figure 5 (a) and Figure 5 (a) show the state when the supplied parts with a square cross section in the normal position are aligned. Figure 4 (b)
and FIG. 5(b) are explanatory diagrams showing the situation in case of incorrect posture. In FIGS. 4 and 5, the gravitational force acting on the center of gravity is shown by broken lines, and the cross section of the supplied part is shown by diagonal lines. FIG. 4 shows the track 4 surface horizontally, and FIG. 5 shows the track 4 surface tilted toward the disk. FIGS. 6 and 7 are explanatory diagrams of a cylindrical supplied part having a circular cross section, with (a) showing a normal attitude and (b) showing an incorrect attitude, respectively.

The parts to be supplied are placed onto the disc l of the revolving parts feeder, and the parts to be supplied are transferred onto the truck 4 from the point where the stored disc l and the truck 4 come into contact, and are transported on the truck 4. and are arranged in a longitudinal direction in one row by the alignment wall lO. The parts to be supplied with incorrect posture are placed on the alignment wall 10.
is pushed towards the inner edge of track 4 by
and falls onto disk 1. If the surface of the track 4 is horizontal as shown in FIG. 4, the supplied parts having a rectangular cross section as shown in FIGS. Since the centrifugal force caused by the rotation makes it more difficult to fall, the width between the alignment wall lO and the inner edge of the track 4 must be made extremely narrow in order to ensure removal of incorrectly positioned supplied parts. Therefore, not only does the rate at which supplied parts in a normal posture fall increase, but also it becomes impossible to completely remove supplied parts in an incorrect posture. As shown in Fig. 5, by tilting the intermediate disk in such a way that the surface of the track 4 in the area where the posture is to be determined is tilted toward the disk l, the supplied parts in the incorrect posture fall from the track 4 to the disk 1. It becomes easier to
The width of the inner edge of the alignment wall 10 and the track 4 can be increased, the efficiency of alignment is increased, and incorrectly oriented parts to be supplied can be completely eliminated. The cylindrical supplied parts shown in FIGS. 6 and 7 tend to roll down on the surface of the inclined track 4 shown in FIG.
For a cylindrical part to be supplied, in which the supply amount of a part in a normal position is reduced, the surface of the track 4 must be horizontal as shown in FIG. In the one shown in FIG. 6, the intermediate disk 20 is horizontal, and the disk 1 is tilted toward the bottom of the fall prevention wall 3 with the contact point with the track 4 at its highest point, so that the center of the disk 1 is The cylindrical supplied parts stored nearby roll on the disk 1 and move to the outer periphery of the disc 1 as the stored amount decreases, so that all the stored parts can be lined up and supplied. In order to realize this method of alignment, the length of the struts supporting the intermediate disk 20 on the base 30 can be made variable.

Embodiment Fig. 8 shows the arrangement of the supports when there are three supports, and Fig. 9 shows the arrangement of the supports with four trees. Figs. The portion where the supplied parts transfer from the disk 1 to the track 4 at the contact point of the track 4 is shown, and the portion surrounded by the broken line is the alignment portion where alignment is performed. In Fig. 8, if the support 31 is attached to the intermediate disk below the alignment part, and the other two wooden supports 32 and 33 are attached to appropriate positions on the intermediate disk, the intermediate disk will be centered at the alignment part. It can be tilted in any direction. When the supports are made of four pieces of wood as shown in FIG. 9, the inclination of the track of the alignment portion can be freely selected regardless of the arrangement of the supports.

Effects of the Invention The present invention has made it possible to manufacture a revolving parts feeder having a track with an optimal inclination corresponding to the shape and characteristics of the parts to be fed, in an optimal shape while aligning the parts to be fed. In addition, it has become easier to change a rotating parts feeder that was previously manufactured for one type of supplied parts to a feeder for a second type, making it possible to respond to changes in production models. . According to this method, the upper structure of the feeder can be made common, and the feeder can be manufactured using a building block method without having to manufacture a feeder each time to align a specific supplied part. Therefore, production costs can be reduced and automated systems can be manufactured at low cost. Therefore, the present invention greatly contributes to automation of production.
